For drivers navigating the roads of Littleton and Highlands Ranch, CO, adhering to Colorado’s stringent emissions testing requirements is crucial. In a nutshell, any light-duty diesel-powered vehicle that is four years old or older must undergo a diesel emissions test to renew its license plates or registration. Despite the routine nature of the test, it is not uncommon for vehicles to fail. If your vehicle fails the emissions test, it cannot be registered, and you can’t renew your license plates until the necessary diesel emissions repairs are made. Fortunately, we at Branch Automotive are here to assist you. We offer a full range of diesel emissions repair services in addition to emissions tests. Let’s delve into what diesel emissions repair involves.
What Are Diesel Emissions Systems?
Diesel engines emit significantly more pollutants than gas-powered vehicles. Consequently, your truck is equipped with a specialized diesel emissions system designed to minimize the release of harmful gasses and exhaust smoke into the environment. This system is crucial, especially when idling for extended periods or running at high speeds.
The diesel emissions system is a complex network of parts that help your engine run cleanly and efficiently. It monitors and controls the volume of emissions and diesel exhaust smoke released into Colorado’s air and helps prevent your engine from overheating. Key components of your diesel emissions system include:
- A Diesel Particulate Filter (DPF) that traps soot particles released by the engine.
- Selective Reduction Catalyst (SCR) that reduces carbon monoxide, nitrogen oxide, and hydrocarbons.
What Are the Most Common Diesel Emissions Repairs?
Branch Automotive is one of the few auto repair facilities in Littleton, CO, and Highlands Ranch, CO, offering both diesel emissions testing and repair services. Common issues we encounter include:
- Contaminated Diesel Exhaust Fluid (DEF) is often remedied by testing and replacing the DEF.
- Clogged DPF or SCR usually requires component replacement, regeneration, or reset parameters.
- A cracked tank, pump, or failed water heater is usually remedied by replacing the damaged part.
- Low fluid problems can be fixed by topping off the fluid and regeneration—if necessary.
- Programming problems often require updates to the system.
- If your truck is stuck in idle-only mode, we need to correct the underlying problem and typically perform regeneration afterward.
- If your truck won’t enter regeneration mode, we must perform diesel emissions system diagnostics to uncover the underlying issue and check for calibration updates.
